The oral stage of swallowing was studied in two groups of 10 cerebral-palsied (CP) children (one drooled and the other did not), and 10 normal children, aged six to 14 years. Small amounts of liquid (0.5 to 1mL) were placed under the tongue or behind the lower lip and intra-oral pressure was measured during the suction and propulsion stages. The CP children who drooled showed no abnormality in the propulsion of liquid towards the pharynx, but all showed abnormal suction of liquid onto the tongue. The difficulty seems to be associated with three types of disturbance: incomplete lip-closure during swallowing, low suction-pressure and prolonged delay between the suction and propelling stages.
对两组年龄在6至14岁的儿童进行了吞咽口腔期的研究，其中一组为10名脑性瘫痪（CP）儿童（一组流口水，另一组不流口水），另一组为10名正常儿童。将少量液体（0.5至1毫升）置于舌下或下唇后方，并在吸吮和推进阶段测量口腔内压力。流口水的CP儿童在将液体推向咽部的推进过程中未显示异常，但在将液体吸到舌头上时均显示异常。这种困难似乎与三种干扰有关：吞咽时唇部闭合不全、吸力低以及吸吮和推进阶段之间的延迟延长。
